- Genetic transport defect
Genetic transport defect: Within the body, many molecules are able to pass across the membranes that surround cells. These molecules can accomplish this feat due to specific transport systems. These systems include special receptors on the membrane of the cell and special carrier proteins. The receptor recognizes the molecule and receives it on the cell […]
- Genetic transposition
Genetic transposition: The ability of genes to change position on chromosomes, a process in which a transposable element is removed from one site and inserted into a second site in the DNA. Genetic transposition was the first type of genetic instability to be discovered. This remarkable phenomenon was discovered by the great American geneticist Barbara […]
- Genetics
Genetics: The scientific study of heredity. Genetics pertains to humans and all other organisms. So, for example, there is human genetics, mouse genetics, fruit fly genetics, etc. Human genetics today comprises a number of overlapping fields, including: Classical or formal genetics — the study of the transmission of single genes within families and the analysis […]
- Genetics, transplantation
Genetics, transplantation: The field of biology and medicine relating to the genes that govern the acceptance or rejection of a transplant. The most important genes deciding the fate of a transplanted cell, tissue, or organ belong to what is termed the MHC (the major histocompatibility complex). The MHC was first identified through tumor transplantation studies […]
- Genital herpes
Genital herpes: An infection by human herpes virus that is transmitted through intimate contact with the moist mucous linings of the genitals. This contact can involve the mouth, the vagina, or the genital skin. Following infection, the virus travels to nerve roots near the spinal cord and settles there permanently. When an infected person has […]
